Thank you all of that does help, but i mean overcoming the intermolecular bonds just using magnets. I do not want to liquify the metal i want it to split into two, or possible stretch it and the whole time i want it to be in a solid state. Anyway as well you said this may only happen in a star...
With metals its not about resistance its about ductility. The ductility of a metal is how easy it is for the atoms to move, metals are ductile because they have delocalised electrons.
I have came up with a theory, it could be completely wrong or not but i had the idea of ferromagnetic decomposition and what i mean by this is breaking a ferromagnetic object apart (such as iron) using magnetism. Is this possible or not?
